isAccessibilityFocusBlocked property
final
whether this node's accessibility focus is blocked.
If true, this node is not accessibility focusable.
If false, the a11y focusability is determined based on
the node's role and other properties, such as whether it is a button.
This is for accessibility focus, which is the focus used by screen readers like TalkBack and VoiceOver. It is different from input focus, which is usually held by the element that currently responds to keyboard inputs.
